Logical Device Fault Status
Words 12 through 15, bits 0 to 7 – indicate the device fault status
for logical racks 0, 1, 2, 3, 8, 9, 10, and 11. Bits 0 through 3 are for
primary/normal devices and bits 4 through 7 are for complementary
devices. Each bit corresponds to a quarter logical rack location. If a
device is not responding to communications, has gone off line, or is
configured to an incorrect logical rack size, all bits corresponding to
the device will be set to 1. This is highlighted in the example below.
